Atomic Orbital - Orbital Names

Orbital Names

Orbitals are given names in the form:

where X is the energy level corresponding to the principal quantum number n, type is a lower-case letter denoting the shape or subshell of the orbital and it corresponds to the angular quantum number l, and y is the number of electrons in that orbital.

For example, the orbital 1s2 (pronounced "one ess two") has two electrons and is the lowest energy level (n = 1) and has an angular quantum number of l = 0. In X-ray notation, the principal quantum number is given a letter associated with it. For n = 1, 2, 3, 4, 5, ..., the letters associated with those numbers are K, L, M, N, O, ..., respectively.

Famous quotes containing the word names:

    The instincts of merry England lingered on here with exceptional vitality, and the symbolic customs which tradition has attached to each season of the year were yet a reality on Egdon. Indeed, the impulses of all such outlandish hamlets are pagan still: in these spots homage to nature, self-adoration, frantic gaieties, fragments of Teutonic rites to divinities whose names are forgotten, seem in some way or other to have survived mediaeval doctrine.
    Thomas Hardy (1840–1928)
